The term that describes when an enzyme loses shape and function.
Answer:
Denature
Explanation:
Denature
Answer:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
ExplanatioEnzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without. However, the catalyst does not change the ∆G for the reaction.
Active sites and substrate specificity
To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates.
In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. In fact, whatever type of biological reaction you can think of, there is probably an enzyme to speed it up!
The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens

What characteristic do all protozoa display?
autotrophic
immobile
vertebrate
eukaryotic
The characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.
What do you mean by Protozoans?Protozoans may be defined as single-celled microscopic organisms that significantly belong to the kingdom of Protista. These organisms are eukaryotic in nature, and hence they have a true and membrane-bound nucleus in order to function properly.
Some protozoans are definitely attached to the substrate or construct cysts. So, they do not migrate around. But some protozoans have the capability to move around at some stages in their life cycles mostly after the cell division.
So, option B is eliminated. Protozoans are heterotrophic as well. They use organic carbon as a source of energy. So, option A is eliminated.
Therefore, the characteristic that all protozoans display is their eukaryotic nature. Thus, the correct option for this question is D.

Answer:
A bacterium has positively supercoiled DNA. This is likely because? A. The bacteria don't normally express their genes. B.
Explanation:
The bacteria normally grow in high temperature condition. So, the correct option is D.
What is Bacteria?Bacteria are defined as tiny, single-celled organisms that are millions of different types of bacteria. Many can be found in and on the body and are beneficial to us. Bacteria lack a membrane-bound nucleus and other internal structures, so they are classified as unicellular life-forms called prokaryotes.
The bacteria in our bodies help break down the food we eat, provide us with nutrients and neutralize toxins that play an essential role in preventing infection by protecting colonized surfaces from invading pathogens.
Thus, the bacteria normally grow in high temperature condition. So, the correct option is D.

what are 4 cellular activities that would require the energy of ATP?
Answer:
active transport (moving particles against the concentration gradient)making proteinscell division (for growth and repair)transmission of nerve impulsesHope this helps!
ATP is the energy currency of the cell and it is required almost everywhere. 4 cellular activities that would require the energy of ATP will be cellular respiration, ion transport, muscle contraction, nerve impulse.
What is the role of ATP ?The role of ATP is providing energy where it gets hydrolysed into ADP along with the phosphate ion where the reaction provides energy and this reaction brings about energy in the activity.
The cellular activities are the activities that take place inside the cell and various activities that will link to them in order to perform various functions. DNA synthesis, biochemical reactions, cellular respiration, cellular activities all takes place with the help of ATP.
Therefore, ATP is required almost everywhere in both cellular respiration activities and cellular activities.

what is the primary pigment that makes leaves green in land plants?
Chlorophyll is the primary pigment that makes leaves green in land plants, by absorbing red and blue light.
What is chlorophyll?It is a pigment present in the plant leaves, through which plant leaves apers green in observation, it plays several roles in the plants other than the green appearance of the leaves.
During photosynthesis, this chlorophyll pigment is responsible to form reaction center through which light is absorbed and leads to a process through which light converts into chemical energy for the synthesis of food.
It is present in the chloroplast, which is the site of photosynthesis, and provides the necessary components for plant food synthesis.
Therefore, the primary pigment that makes leaves green in land plants is known as chlorophyll.

Pollution
The stream runoff from small watersheds feeds into larger streams and rivers. The sun evaporates some water back into the air as it inflows into streams, rivers, and oceans.Wetlands' highly developed root systems hold the soil in place and filter pollutants, naturally improving water quality (including water that is eventually used for drinking).Contaminants present in these surface waters can contribute to contamination of the groundwater system. Some wells rely on artificial recharge to increase the amount of water infiltrating an aquifer, often using water from storm runoff, irrigation, industrial processes, or treated sewage.Heavy metals and other contaminants can accumulate in seafood, making it harmful for humans to consume. Microplastics can be ingested by fish and other species that filter their food out of the water.The salinity of the ocean varies from place to place, especially at the surface. Much of the ocean has salinity between 34 ppt and 36 ppt, but there are places that tend to be higher or lower.How is pollution caused?
Pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes, and wildfires.

Explain how fitness can change the allele frequency of a population. PLZ no link
Answer:
Natural selection can cause microevolution (change in allele frequencies).
Explanation:
With fitness-increasing alleles becoming more common in the population.
Fitness can affect the survival and reproduction rates of individuals with different alleles, leading to differential contribution to the next generation and changes in the frequency of these alleles in the population.
What is fitness?Fitness is a measure of the reproductive success of an individual within a population. The fittest individuals are those that are most successful at passing their genes on to the next generation. When the environment changes, the selective pressures on a population also change. This can lead to changes in the relative fitness of different individuals, and thus changes in the allele frequencies of a population over time.
For example, if a population of birds lives on an island with small seeds, those birds with small beaks may be more fit than those with larger beaks. This is because they are better adapted to the environment and can more easily obtain food. Over time, the frequency of the small-beaked allele will increase in the population, while the frequency of the large-beaked allele will decrease.
Thus, fitness can drive changes in the allele frequency of a population over time by favoring those individuals with alleles that are better adapted to the environment.

Answer:
No.
Explanation:
No, solute molecules are larger in comparison to solvents, so they cannot pass through the semi-permeable membrane.
Answer:
Nope Nope Nope, They cannot pass through it
Explanation:
Osmosis describes the diffusion of the solvent through a semipermeable membrane. The driving force of the solvent shift is the concentration difference of solutes in the solutions separated by the semipermeable membrane. In contrast to solvent, solutes cannot pass this barrier.
